Different versions of Lua and error in the same versions of ConTeXt (Fedora vs Win7)

I think TeX Live 2014 uses Lua-5.2.3 on all platforms.
I don't know differences between 5.2.2 and 5.2.3.
Current windows version of standalone ConTeXt also uses 5.2.3.

Best,
Akira

Different versions of Lua and error in the same versions of ConTeXt (Fedora vs Win7)

[Jaroslav Hajtmar]

Hi ConTeXist...
How can I find out what version of Lua uses ConTeXt TeXlive 2014 
respectively what version of Lua uses Standalone ConTeXt?
The point is that Pablo Rodriguez use Fedora 20, which comes with 
Lua-5.2.2. Pablo tested last version of my module ScanCSV and his 
current version of standalone ConTeXt gained mistake, while I compiled 
(with the same current version of Standalone under Win7) the same source 
code without error ....

Error message from log file is:

t-scancsv-2015-02-19.lua:81: assertion failed!
stack traceback:
     [C]: in function 'assert'
     t-scancsv-2015-02-19.lua:81: in function 'ParseCSVLine'
     t-scancsv-2015-02-19.lua:123: in function 'parsecsvdata'
     t-scancsv-2015-02-19.lua:180: in function 'opencsvfile'
     [\directlua]:1: in main chunk


Thanx
Jaroslav Hajtmar

[Jaroslav Hajtmar]

Hans, thanks for the reply. You write about the embedded CSV scanner. I 
was looking at contextgarden and on the Internet too, but I did not 
found any information about this.
Can you, please, about built-in scanner CSV say more (link, minimal 
example etc.)? This thing interests me very much...

Thanks
Jaroslav Hajtmar

Hans,

I don’t really need this at home, but I’m interested in this.

I guess you mean m-database.mkiv. But I don’t have a clue on how to
handle it.

I mean, how to ignore the first line and how to make commands from the
so-called cells (A2, B5...; to use them in document combination) reading
an external file.

Many thanks for your help,

Pablo

there are several variants, here is one:

\starttext

\startluacode

local mycsvsplitter = utilities.parsers.rfc4180splitter()

local crap = io.loaddata("c.txt")

local list, names = mycsvsplitter(crap,true)   inspect(list) inspect(names)
local list, names = mycsvsplitter(crap)        inspect(list) inspect(names)

context.starttabulate { "|l|r|" }
for i=1,#list do
     local l = list[i]
     context.NC() context(l[1])
     context.NC() context(l[3])
     context.NC()
     context.NR()
end
context.stoptabulate()

\stopluacode

in addition to the previous mail, t.txt is:

first,second,third,fourth
"1","2","3","4"
"a","b","c","d"
"foo","bar""baz","boogie","xyzzy"

the code is in util-prs.lua (where all kind of parsing code lives)

if you want to use that kind of code outside context you can do 
something like this:

lua mtxlibs.lua --selfmerge foo.lua

and then in your script load foo.lua

this makes it possible to use the same set of helpers in context as well 
outside it (alternatively you can just use luatex as lua engine and 
mtxrun as script runner which is what we mostly do); this means that the 
context distribution provides all kind of means to set up workflows

Thanks for showing options in last mails. This is for me very 
interesting news, and certainly it will be very useful and inspirative 
for me.

Re: Different versions of Lua and error in the same versions of ConTeXt (Fedora vs Win7)

[Jaroslav Hajtmar]

Hi Hans.
One more I ask You about this thing. When I have other separator - for 
example ";" then c.txt data file is:

first,second,third,fourth
"1";"2";"3";"4"
"a";"b";"c";"d"
"foo";"bar""baz";"boogie";"xyzzy"

I was unable to figure out how to set the separator (and others default 
values too) so as to replace the default value in the library util-prs.lua
Is there anything as utilities.parsers.rfc4180splitter.separator=";"???

This library is loaded automatically? Or as a module?

Thanks Jaroslav Hajtmar

Here is minimal example for Your correction:

\starttext

\startluacode

local mycsvsplitter = utilities.parsers.rfc4180splitter()
utilities.parsers.rfc4180splitter.separator=";"

local crap = io.loaddata("c.txt")

local list, names = mycsvsplitter(crap,true)   inspect(list) inspect(names)
local list, names = mycsvsplitter(crap)        inspect(list) inspect(names)

context.starttabulate { "|l|r|" }
for i=1,#list do
     local l = list[i]
     context.NC() context(l[1])
     context.NC() context(l[3])
     context.NC()
     context.NR()
end
context.stoptabulate()

\stopluacode

\stoptext
